Torque Converter Hydraulic Circuits (TCC Released)
When the TCC is released, the TCC charge limit valve opens the LPX hydraulic circuit to the CCL circuit through the CRLX circuit. The CCL circuit provides fluid to the torque converter. Transmission fluid exits the torque converter through the COUT circuit and circulates through the transmission cooling system.

Torque Converter Hydraulic Circuits (TCC Applied)
To apply the TCC, the TCC solenoid applies regulated solenoid pressure to the TCC charge control valve and the TCC apply regulator valve to move the valves. Line pressure is supplied by the manual control valve to the TCC apply regulator valve through the NDX circuit. As the TCC apply regulator valve moves, it opens the NDX circuit to supply the CAPY circuit with regulated line pressure to apply the TCC.
Line pressure is supplied to the TCC apply regulator valve. The TCC apply regulator valve directs regulated line pressure to the TCC through the CAPY circuit to apply the TCC. CAPY also supplies regulated line pressure to the opposite side of the TCC apply regulator valve for controlled TCC engagement.
